I designed a system like picture. In the picture, I set 2 PID tuner. The question is "what is control region of the first PID controller". Does the PID controller control whole block before the feedback point?

Why would it? I don't see any signals going from the first PID controller block back to the "whole block before the feedback point" so how could it control it?

The PID Tuner considers as the plant all blocks in the loop between the PID Controller block output and input.
